Hi, I have had a problem for many months where esd segfaults on two |
| 2 |
systems. Sound and alsa (alsa-lib is 1.09) work fine. In the past |
| 3 |
there were esd-alsa API problems, but they have been solved - right? |
| 4 |
|
| 5 |
strace shows nothing obvious up until the segfault. Where can I look |
| 6 |
next? |
